This invention relates to an animal poke for use in preventing livestock from breaking down or moving through wire fences. It is wellknownthat cattle, attracted by growing` crops in "ad'acent fields oftenforce a passage through ences, and since these fences are generallyconstructed by use of lines of Wire stretched between posts set'atintervals, the electrical poke to be described herein operates to greatadvantage, the wire of the fence when engaged by the poke, causing thecompletion of an electrical circuit and resulting shock to the animal,thislshock, while not causing physical injury, being" suicient to causepam and tending to prevent any further attempt on the part of the animalto move through or to interfere with a fence.

'l T he invention includes an animal poke consistin of few and simpleparts which may be manu actured at a limited cost, will be convenientand durable in use andwill be eective for the purposes mentioned. v

t With the foregoing objects'andothers in view the invention presents anew anduseful construction, comblnation and arrangement of arts asdescribed herein and claimed, and' as 1llustratedin the accompanyingdrawing, it being understood that changesmay be made in form, size,proportion of parts and'minor details,l said changes bein ,within thescope of the invention as claimed.

In the drawing, Fig. 1 is a plan view of a electrical animal pokeembodying my invention, the induction coil and electrical conductorsbeing diagrammatic to clearly ex lain operation. Fig. 2 is a ers ectiveview s owing the device applied) an ready for operation.- Fig. 3 -is anenlarged section on line 3-3 of Fig. 1. Fig. 4 is a diagram showingelectrical connections.

Referring now to the drawing for a more particular, description, theinvention con-. s1sts, in part, of a pair :of arms 6 having suit-4 ablecurvatures between their ends so'that,

when connected at their ends a yoke or poke Will be provided which willit the neck of the animal without undue chaiing, said arms bez inextended a suitable distance above and be ow the curved portions asshown'im` Fig. 1

structing" parts which engage the wires one of the-wires if the headioftheanimal other-fibrous material. ANumerals 7 fandinprojects throughthe fence between ftherwire's. l.

These arms may be constructed ofwoodor dicate a pair ofmetallic, linin sor casings whichare secured by any suita le means-ite the arms. r These-casings'may be constructed of thin sheet metal and are disposed atthefront. and inner sides of the arms and` are depended upon lfor operationsince they oplt will be noted that these'casingsdo not cover theendpo'rtions' of the arms` 6 and therefore `'said -casings areelectrically insulated relative to each other. Numeral 9 indicates ahinge which connects the upper ends of arms 6 and the lower ends of saidarms may\be connected by-a strap l0 and buckle. a v

Y As thusdescribed, a yoke or poke is provided consisting of parts which`may extend below andabove the neck so that these extensions willencounter the wires of a fcnceif the animal attempts to passtherethrough, the

metallic strips 7 and 8 being-so disposed on the arms that they-mayengage said wires. Numeral '11v (Fig. 5) mdlcates, by broken lines, onelof the wires of a fence.

Any suitable arrangement ofl parts may be made for causing an electricalshock to the animal-upon lcompletion of anelectrical circuit, thewire11. operating asa switchfor closing the circuit. For `this purpose Ihave lshown an electric battery. 12 which is secured :toene the arms 7or 8 at the lower end of the poke and also have shown an induction vcoil; 1B (F ig. 4).., the primary and secondary coils thereof, forconvenienceof description,

.being respectively indicated at 14 vand 715, a -buzzeror vibratorvbeing indicated at 1.6. The

electric battera and induction coil as well as electrical 4con actorstobe described are, of

course, suitably housedfr'om the weather and carriedbythe,peke...f1Numerals 17findicate a .y .pair of metallicv plates eachbeing mounted'b'y any-suitable meansjupona metallic 'casing at the-inner l side thereof. These; members 17 may consist ofithin, metallicstrips so that they 'will not cause ychaing ofy theskin .fand-D100preferably they are disposed near the upper lart of the curved portionsof'the poke 'as st shown in Fig. 1 of the drawing, so that they willengage theskin of the animal. Nu-

'merals 18 indicate insulating-strips which are disposed between theplates 17 `and metal- 'lic casings 7 and 8. Y

Numeral 19 indicates an electrical conduc- 'I tor leading from one poleof the battery 12 to the metallic casing 7, and an electrical conductor20 leads from the opposite pole of the battery 12 to the primary coil14. Numeral 21 indicates an electrical conductor in communcation withthe secondary coil 15 and which communicates with the metallic strip 17of casing 7, and at 22 is indicated an electrical conductor which is incommunication p with the metallic plate 17 of the casing 8 and incommunication with the secondary coil 15. A conductor 23 leads from theprimary coil 14 to the casing 8. v

One advantage in the use of the vibrator 16 is that it will cause asuccession of shocks which will continue .until the animal backs` awayfrom the fence to discontinue a contact of the casings 7 and 8 with afence wire 11.

" It will be seen that the electric battery will not be called into useexcept when an electrivcal circuit has been established by an electricalcommunication of the metallic casings, one

with the other, and therefore changing or recharging of the electricbatterywill not be required except at long intervals of time.

I claim .as my invention,
